I was doing about 6500- 6700 rpm on the banks- not quite the 7000-7200 it should have been pulling but it was very windy that day and I'm not sure we had the gearing spot on. You bounce around like crazy on the banking and the very strange sensation of being partially upright and not perpendicular to the banking while wide open is very odd and takes some getting used to. Better to just turn your brain off and just keep it pinned.

...and that speed that you atained was?

[Doug MacRae]

There was a speed gun at Daytona and I only had readings for the one race with a best of 126 mph. It was a very windy day there, I'm not sure which end they had the gun at.

[Peter Balfour]

That was awesome footage, all except for the part where the bike decided not to play any more ! Did you have the GoPro camera mounted on your helmet? I got one of those cameras amd tried to mount it on the fairing of my BSA B50 but the vibration distorted the picture badly.

Peter,

I SURE HOPE it wasn't mounted on his helmet!!!! Notice how, in the video, you can see the rider lying on the track about 50' away from the camera!!!

Good point there Brian ! I need another coffee....I guess if it was on his helmet he would need head re-attachement surgery which I don't think is perfected yet . Apparently, Nortons don't vibrate like BSA singles!

Peter

[Doug MacRae]

My Norton vibrates like an industrial paint shaker while idling and then smooths out fairly nicely when the revs go up. In the Roebling video ( http://www.youtube.com/watch?v=EuYrHKk9STA ), while on the grid the camera seems to compensate for this vibration by turning the shakes into a sort of 'heat wave' look. I was surprised how well this looked, I assumed the camera footage while idling would be unwatchable. I mounted the camera in front of my tach on the flat part of my fairing.

[Peter Balfour]

I mounted my camera in the same location you did Doug but my videos so far have been pretty well unwatchable: http://www.youtube.com/watch?v=p7lsgcVZagU

It may be how that section of my faring is mounted, I may have to secure it a little better. Your videos have the same shake at idle but look great once you get going. Something else to play with!

Peter

[Doug MacRae]

I think a more sturdy fairing mounting might cure it... Things are certainly moving around too much.

[Ray Roberts #115]

Peter, I told you before, the B50 will shake all your fillings out of your teeth so the poor camera has got no chance.
Ray.

[Peter Balfour]

You're 100% correct Ray, but luckily all fillings are accounted for so far ! Maybe my top secret winter upgrades will help with keeping all fillings in place....time will tell.

Not to pirate your thread here, but since we're on the subject of Go Pro Wide Feedback/Sound Quality Issues, I've tried to get better engine sound without the noise on my Go Pro Wide, even with the door seal removed, and a piece of tissue taped over the microphone holes, but it still gives off static feedback. Forget recording on HI. Here's the latest of the camera mounted on a friend's SV650, no tissue over mic holes, but door seal removed, recording on LO.

Hey Doug, I was at Herbs last night dropping off some stuff I need done and I saw your bike. Actually, the damage to the chassis is minimal, the engine casings are a bit messed up though. Amazing what one little stud will do to an engine at high rpms. Looks like she will be up and running in no time, tough bikes those Nortons!

That's what I was thinking too the last time I over reved and blew up a motor.....
